Figure 2. Identification of purified α1-PI protein in the database.

Figure 2

(A) Amino acid composition search using the Swiss-Prot Database. Comparison of amino acid composition ratio between theoretical and purified α1-PI. Data entry for the search is as follows: species, isoelectric point (pI) range, molecular weight range, and 18 amino acid molar percentage values. (B) Direct protein identification by LC-MS/MS analysis. Peptides identified as part of α1-PI protein by the Mascot database search are underlined.
